| 摘 要： | 以有机质含量相同的猪粪、沼渣为基肥,以N,P,K含量相同的化肥与沼液为追肥,以L402番茄为供试作物,采用二裂式区组设计的方法.研究了沼肥、猪粪、化肥等不同施肥组合对设施土壤固氮菌动态变化的影响.试验结果表明:随着番茄生育期的推进,各施肥处理土壤自生固氮菌的数量逐渐增加,基施沼渣比基施猪粪有利于促进土壤自生固氮菌的生长;从番茄苗期到成熟期,追施化肥土壤自生固氮菌数量多于追施沼液土壤,猪粪与化肥配合施用、沼渣与沼液配合施用分别较猪粪与沼液配合施用、沼渣与化肥配合施用能更好地促进土壤自生同氮菌的繁殖.

| Abstract: | The paper studied the effects of the combination of biogas fertilizer,pig manure and chemical fertilizer on nitrogen-fixation bacteria in greenhouse soil.In the experiment,L402 tomato is chosen as sample,split-plot design is adopted and pig manure,biogas sludge are utilized as base fertilizers in which the organic matter contents are equivalent,chemical fertilizer and biogas slurry are used as top fertilizers in which the N,P and K contents are equivalent.The results are as followings:along with growth prog... |
